We have added the following note: Tested on iOS 26.1 release: The following effects can be observed, if for the locale en-US, an Apple voice is selected (e.g. Evan): Speech Controller (Read & Speak -> Speak Screen -> Show Controller) play button reads with selected Apple Voice (i.e. not the Apple default voice Samantha) the Swift API method AVSpeechSnythesisVoice(language:) still returns "Samantha" (bug !) To observe the reported bug, you really need to install a 3rd party voice, i.e. a non-Apple voice. You can test it without subscription fee with e.g. Símarómur on the App Store: https://apps.apple.com/is/app/s%C3%ADmar%C3%B3mur/id6745481689 Install Símarómur, select the "Steinn" voice in Accessibility -> Read & Speak -> Voices -> English -> Steinn (en-US). Test functionality of voice via pressing "Play" Button inside the Settings (works). Then try to use the Speech Controller to read an English Text e.g. in the Safari browser -> Suddenly uses Samantha again. Directly addressing com.grammatek.simaromur.extension.Steinn_US works without problems, which e.g. the Símarómur app uses internally.

Interesting. Do you have any further links or reference for this ? This is not only in the betas, it's a bug of iOS 26.0 directly as well.

Hi, could you post the result of the Bug report here ? We don't have access and it would be really helpful to know the outcome. Thx !

Yes, for me the key was using jpeg as well ! PNG doesn't work.
